Flexible and Accurate Transparent - Object Matting and Compositing Using Refractive Vector Field
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
In digital image editing, environment matting and compositing are fundamental and interesting operations that can capture and simulate the refraction and reflection effects of light from an environment. The state‐of‐the‐art ...
Fast Mean‐Curvature Flow via Finite‐Elements Tracking
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
In this paper, we present a novel approach for efficiently evolving meshes using mean‐curvature flow. We use a finite‐elements hierarchy that supports an efficient multigrid solver for performing the semi‐implicit ...
Efficient Depth‐of‐Field Rendering with Adaptive Sampling and Multiscale Reconstruction
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
Depth‐of‐field is one of the most crucial rendering effects for synthesizing photorealistic images. Unfortunately, this effect is also extremely costly. It can take hundreds to thousands of samples to achieve noise‐free ...
A Survey on Shape Correspondence
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
We review methods designed to compute correspondences between geometric shapes represented by triangle meshes, contours or point sets. This survey is motivated in part by recent developments in space–time registration, ...
Improved Model‐ and View‐Dependent Pruning of Large Botanical Scenes
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
We present an optimized pruning algorithm that allows for considerable geometry reduction in large botanical scenes while maintaining high and coherent rendering quality. We improve upon previous techniques by applying ...
Extending Backward Polygon Beam Tracing to Glossy Scattering Surfaces
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
Backward polygon beam tracing methods, that is beam tracing from the light source (L), are well suited to gather path coherency from specular (S) scattering surfaces. These methods are useful for modelling and efficiently ...
Diffusion‐Based Snow Cover Generation
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
We present a method to generate snow covers on complex scene geometries. Both volumetric snow shapes and photorealistic texturing are computed. We formulate snow accumulation as a diffusive distribution process on a ground ...
A Linear Variational System for Modelling From Curves
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
We present a linear system for modelling 3D surfaces from curves. Our system offers better performance, stability and precision in control than previous non‐linear systems. By exploring the direct relationship between a ...
Implicit Hierarchical Quad‐Dominant Meshes
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
We present a method for producing quad‐dominant subdivided meshes, which supports both adaptive refinement and adaptive coarsening. A hierarchical structure is stored implicitly in a standard half‐edge data structure, while ...
Scale Space Meshing of Raw Data Point Sets
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
This paper develops a scale space strategy for orienting and meshing exactly and completely a raw point set. The scale space is based on the intrinsic heat equation, also called mean curvature motion (MCM). A simple iterative ...
